Phthalocyanine (PC) pigments constitute a broad class of pigments. PC Blue and PC green are among the most important organic pigments.

Copper phthalocyanine blue is the copper (II) complex of tetra aza tetra benzoporphine (CPC) whereas Phthalocyanine green is its chlorinated derivative (Pigment green 7). The brominated derivative of CPC provide a yellowish green shade(Pigment green 36).

The specific crystal modification decide the hue of the product as in Alpha blue - red shade copper Phthalocyanine (Pigment Blue 15) and in Beta blue - green shade blue (Pigment Blue 15:3). The Alpha modification which is phase stabilised by partial chlorination called solvent stable alpha blue or Pigment Blue15:1.

The Alpha modification which is stabilised towards flocculation and the phase change are registered as Pigment Blue 15:2. These pigments find use in paints.

The details of the individual class of pigments together with its application is given separately.
